我是一名平面设计师，刚刚学习 SVG 动画图标和编码。我在 illustrator 中对一杯咖啡进行了说明，然后将其导出为 SVG 文件。我正在尝试为 Steam 设置动画，使其像真正的 Steam 一样上升。问题是，即使我在 CSS 中选择了 .steam1 .st1 ，它也不会为 Steam 设置动画。我可能真的对我一直在看的教程数量感到困惑。有人可以查看我的 HTML 代码以获取插图并帮助我使用基于此代码的 CSS 正确设置动画 http://codepen.io/anon/pen/DLmCn
这是我在 HTML http://codepen.io/anon/pen/niHCA 中的 SVG 代码

最佳答案
这是基于您的代码的快速起点:http://codepen.io/anon/pen/rAdom?editors=101
首先，定义动画的关键帧:
@keyframes steaming {
0% {
transform: translateY(0px);
opacity: 0;
}
50% { opacity: 1; }
100% {
transform: translateY(-10px);
opacity: 0;
}
}
@-webkit-keyframes {
...
}
Steam 将开始不可见(不透明度:0)，然后淡入(不透明度:1)并在向上移动时退出，由 translateY(-10px) 确定。请注意，像素值根据 SVG View 框和高度/宽度值进行缩放。
然后，使用您设置的类将这些关键帧应用于每个 Steam SVG 元素:
.steam1{
-webkit-animation: steaming 7s linear infinite;
-moz-animation: steaming 7s linear infinite;
animation: steaming 7s linear infinite;
}
您可以调整动画速度以使其看起来更好一些。
